OTTO UNZICKER, OF CHICAGO, ILLINOIS, ASSIGNOR TO ADOLPH SHOEN- INGER, OFSAME PLACE.

VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 242,490, dated June '7,1881.

Application filed February 2l, 1881.

To all whom it may concern Be it known that I, OTTO UNZIcKER, ofChicago, in the county of Cook and State of Illinois, have invented acertain new and use- 5 ful Improvement in Velocipedes, of which thefollowing is a specification.

The object I have in view is to produce a sprin g-seat for veloci pedeshaving two or more wheels, which seat will be simple and cheap 1 o inconstruction, can be readily secured in place, and will be exceedinglystrong and durable in use.

My invention therein consists in the peculiar device employed by me forthis purpose,

1 5 as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figurcl is a sideelevation of the head of the velocipede, the fork-standards and .20 backbars being broken off; Fig. 2, a vertical section of the parts, takenthrough the seat and its arm; Fig. 3, across-section on line3 3, lookingtoward the fork-standards; and Fig. 4, a cross-section through theseat-arm and its 2 5 holding-bolt, the seat and back bars not beingshown.

Like letters denote corresponding parts in all four gures.

The round fork-standards A are secured togethcr at their upper ends bythe cast-metal head B, through the side arms of which bolts pass toplates a on the forward sides of the standards, such plates forming,with the arms of the head, sockets for receiving the standards. Thecast-metal head B rises above the standards A, and has the handle Csecured to its upper end.

The round back bars, D, at their upper ends, are secured betweensocket-plates E E. The lower socket-plate, E', has a pointed stud, b,projecting therefrom, which rests in a socket, o, formed in a cross-barconnecting the side arms of the head B.

From the upper socket-plate, E, rises a block, 4 5 F, having a conicalsocket, d, in its upper end. A set-screw, c, held by a jam-nut, c',turns through an upper cross-bar, f, of the head B, and has a conicalpoint, which enters the socket d. By adjusting the screw e all wear inthe (No model.)

joint can be taken up. In this manner the back bars and fork-standardsare pivotal] y connected.

G is the seat-arm, made preferably of malleablecast-iron, as are theother metallic parts of the velocipede. To the rear end of this arm issecured the stuffed or cushioned seat H. The forward end of thearrn G isforked, and is constructed to form two upwardly-turned hooks, g, whichengage with horizontal studs h projectin g from the sides of the blockF.

At or near its center there extends downwardly through the arm G asingle bolt, I, which passes through the plate E between the back bars,D, and screws into a nut, i, on the under side ot' such plate E. Thisnut is held vin position and prevented from turning by 'projectionskcast on the plate E, which projections are hammered and bent upon thenut.

Between the arm G and plate E there is placed upon the bolt I a rubberor metal spring, K, which gives elasticity to the seat-arm and seat.

In attaching the seat-arm to the velocipede it is only necessary to hookits forward end with the studs h and turn the bolt I through the arm andspring into its nut. The seat arm can bc detached with equal facility bysimply removing the bolt I.

The bolt I, in addition to securing the parts, limits the expansion ofthe spring and the upward movement ot' the seat. This spring-seat, itwillbe seen, while having the necessary elasticity, is strong, cheap,and can be readily applied. It also has the advantage that the springcan be easily replaced, when worn out, at small expense.

My spring-seat can be used on bicycles as well as on velocipedes withthree or more wheels, and can be applied to tricycles of differentconstruction from that shown and described.

What I claim as my invention isl. In a velocipede, the rigid seat-armGr, pivoted at its forward end to the back of the velocipede andextending rearwardly wholly above said back, in combination with thevertical spring K, placed between such rigid seatarm and thevelocipede-back, and the vertical 1o substantially as described andshown.

3. In a velocipede, the combination, with the seat-arm G, pivoted at itsforward end, ot' the spring, K, the bolt I, and the nut i, held byprojections k on the under side of the plate E, substantially asdescribed and shown.
